python matplotlib pip install amazon ec2

Question

I am trying to install matplotlib on my ubuntu aws ec2 instance:

sudo pip install matplotlib

I did install these:

sudo apt-get install libpq-dev python-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libffi-dev

and I still get this error:

ubuntu@ip-102-21-11-112:~$ sudo pip install matplotlib

Answer 1

Check the first line of your error, it clearly states:

The directory '/home/ubuntu/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

So try:

sudo -H pip install matplotlib

Also check if you have installed setuptools.

Answer 2

you need:

sudo apt-get install gcc
